IOMeter - Average Transaction Time (rev 1)

Back with the Kingston SSDNow V Series 40GB review, I revised the layout of these graphs to better show SSD latency and access time.  First, I have removed HDD results as they throw the scale too far to tell any meaningful difference in the SSD's you are trying to focus on.  Second, I have reduced the queue depth scale down to 4.  In practical terms of a running OS, queue depth is how many commands are 'stacked up' on the SSD at that time.  An SSD is so fast at servicing requests that typical use will rarely see it increasing past 4.  In the cases where it does, there is so much going on that you are more concerned with IOPS and throughput at that point than transaction time.  The below charts are meant to show how nimble a given SSD is.  Think of it as how well a car handles as opposed to how fast it can go.

Some notes for interpreting results:

  • Times measured at QD=1 can serve as a more 'real' value of seek time.
  • A 'flatter' line means that drive will scale better and ramp up its IOPS when hit with multiple requests simultaneously.

Just wanted to mention that according to Paul Thurrott on one of his Windows Weekly podcasts he mentioned file copy , etc. is DRAMATICALLY faster on Windows 8 compared to any previous versions of Windows.
Would love to see the test results on a Windows 8 machine.

The batch copy we perform is conducted from the command line. It is not subject to the overhead of copying via Windows Explorer, which is what saw a *significant* improvement in Windows 8.

We reviewed the standard 840 here, in addition to the 840 Pro.
